Application led February 9, 1912. Serial No. 676,629.

Toall whom 'it may concern:

Be' it known that I, EDMUND M. REDDY, a citizen of the United States,and residing at Ossining, in the county of Westchester and State of NewYork, have invented certain new and useful Improvements in Ceilingutlet-Boxes, `of which the following is a specification, such as willenable those skilled in the art to which it appertains to make and usethe same.

This invention relates to what are known as, outlet boxes, used inwiring a lire-proof or other building for electric lighting and.

other purposes, and the object thereof is to provide an improved deviceof this class designed for use as a ceiling outlet box, and inconnection with chandeliers and other hanging apparatus, and with thisand other objects in view the invention consists in a device of theclass specitied, constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specitication of whichthe accompanying drawing forms a part in which the separate parts of myimprovement are designated by suitable reference characters in each ofthe views, and in which Figure l is a cross sectional view of a floorand ceiling construction showing the method of using my improvementg-Fig 2 a top plan view of vmy improved outlet box, and Fig. 3 a bottomplan view thereof.

ln the drawing forming part of this specitication I have shown a floorand ceiling construction involving ordinary I-beams a together with theusual concrete l), and t-he fiooring c laid on ashes or similar materialc2 placed on the concrete. In forming the concrete part of the floor andceiling construction a wood frame or support is provided consisting of,boards 1l-(Z2 and d3 placed as shown so as to provide a sort of moldinto which the concrete is poured, and this part of the drawingisintended to illustrate the method of using my improved ceiling outletbox e.

rThe outlet box e is rectangular in horizontal section, in the form ofconstruction shown, but may be of any desired shape, and is open at thetop when in use, and provided with a bottom e2 having a centraldepending rim c3 of less transverse dimensions than the body of the box,and preferably abut one fourth the depth of said body of the box. rlhebottom c2 of the box is provided with spaced holes f which are normallyclosed by plates f2 inthe usual man-- ner but which, when the box is putin use, are broken out so as to leave the holes f or a part thereof freefor the passage of the lead pipes g, which are used in the usual manner,and the end portions g2 of which are bent `downwardly through the boxand passed through the openings f two of said pipes being thus shown inthe drawing. The center of the bottom of the box is also `provided witha central opening or hole z,

similar to the holes f, but which is intended to serve as an attachment,or means of attaching a threaded plug h2, which plug serves as a supportor attachment for an electric, or any other illuminating hanger,lighting device, or other article. The plug h2 may be passed downwardlythrough the bottom of the box as shown, and may be secured by means ofscrews h3, or said plug may be secured to the bottom of the box, theonly object of said plug, as hereinbefore stated, being to serve as asupport and attachment for a chandelier or other hanger.

In practice the box is irst placed in position on the board .or boardsd. The pipes g are then placed in position, as shown inFig. 1, afterwhich the concrete is filled in up to` the tops of the -beams a, and inthis operation the box e is also filled with concrete, after which thefloor-ing consisting of sleepers c3, ashes or other suitable materialc2, and the fioor boards c is placed in position, and this completes theoperation, of forming the floor and ceiling construction, it beingunderstood that after the concrete has had time to set or become hard,the supporting or molding boards 1l-Z2 and d3 are removed, whichoperation leaves the bottom rim c3 of the box, the plug 71,2, and theends vg3 of the tubes g exposed, and a chandelier of any kind may besuspended from the plug ft2 and electric wires passed through the tubesg in the usual manner. It lwill also be understood that my improvedoutlet box may be used as a combination gas and electric fixture, ifdesired, all that is necessary being to pass a gas tube through thecentral opening h in thebottom of the box instead of the a plug h2 orsaid gas tube may be passed -through said plug.

rlhis improvement provides a perfectly safe, permanent and practicaloutlet box, and one which may be much more conveniently used in a floorand ceiling construction than' most other devices of this class, as nowconstructed, and my improved outlet box, used as described, avoids thenecessity of cutting in to the concrete in order to place the box, afterthe concrete Work has been finished.

The bottom rim e2 of the box is secured in position by means of screws iin the form of construction shown, but this maybe done in any desired.manner, and in practice the body of the box, When not in use, may beprovided with a detachable cover if desired, and changes in andmodifications of the construction hereinbefore described may be made,Within the scope of the appended claim, Without departing from thespirit of my invention or sacrificing its advantages.

of the box being also provided with pipeapertures or' openings, and witha central opening to receive a hanger attaching device. In testimonythat Lolam the foregoing as my invention I have signed my name in.

presence of the subscribing 'Witnesses this 8th day of February 1912.
